interpretability might be the most important scientific problem in the world right now, as I don't think we can solve alignment if we don't know what we're building. I think I have good news about it. I co-authored early work in mechanistic interpretability at OpenAI and came away pessimistic, because neural networks appeared to fold into arbitrary tangled knots. years later, I started openai's first large-scale automated interpretability project, finding about 2% of neurons legible with the primitive tools we had with modern agentic tools and a much closer look, the picture looks totally different. the vast majority in models up to trillions of parameters are legible, and their circuits beautiful. many famous examples of tangled neurons turned out to be misunderstood. The roadblocks I expected mostly aren't there. I now think ambitious interpretability will be solved by the time we need it most, and possibly quite soon, as automated scientists keep improving. it may be a bitter lesson for interpretability: the simple thing, at absurd scale, works https://already-clean.goodfire.com/

Four Gemini 4 Argon agents, one shared Minecraft world, one goal: defeat the Ender Dragon. 27 hours and 2,783 self-written programs later, the dragon fell. https://x.com/i/article/2111007444981645312

Beam is now available across platforms, with open weights under the Apache 2.0 license - in collaboration with an ecosystem of 40+ partners. We're releasing: - Weights, tokenizer, and reference implementation - BF16, FP8 and NVFP4 weights and a DFlash2 drafter - The open source harness we built and trained Beam on: Mirror CLI Weights and model card on Hugging Face: https://huggingface.co/reflection

Open Source AI Week started with a handful of events and a community bringing people together. Now in its third year, we have 65 events on the calendar—and we kick off tomorrow! Explore the lineup: https://opensourceaiweek.com/ Four highlights: 🎉 Tomorrow, Oct 16: Official Kickoff Party, hosted by Hugging Face https://luma.com/OpenTogether 🛠️ Saturday–Sunday, Oct 17–18: ExecuTorch Hackathon https://luma.com/executorch-hackathon 🎙️ Monday night, Oct 19: Open Weight Debates https://luma.com/592fcwx2 🏆 Next Friday, Oct 23: Open Source AI Awards Night, capping off the week https://luma.com/7ebvz0oq The Open Intelligence Foundation (@open_intel_fdn) is proud to be this year’s organizer, alongside a dedicated volunteer team and 32 backing organizations. Our commitment: • Official events will always be free and community-run. • We’ll work to bring the community together to plan diverse, high-value events at no cost, accessible to everyone. • We will never decline an event because it overlaps with one of ours. That goes against the spirit of open source and community. A shared calendar should create more opportunities to participate, collaborate, and learn. I’m proud to have been involved this year and grateful to everyone who made it happen. Thank you to our sponsors: @GoogleDeepMind, @Azure, @arcee_ai, @SemiAnalysis_, and @NEARProtocol Foundation. And our event hosts: @github, @fdotinc, @hackersquadio, @OSS4AI, @Qualcomm, @AIatMeta, @huggingface , @allen_ai, @MiniMax_AI, @UnslothAI, @PrimeIntellect, @NousResearch, @openclaw Foundation, @vllm_project, @lmsysorg, @inferact, @radixark and @anyscalecompute.
